Social Distancing for DA1469x and DA14531

Tue, 2020-09-22 09:09 -- PM_Dialog

A new page is now available on the Dialog website which contains both the DA1469x and DA14531 Social distancing applications.

The first has been created on top of the SmartBond Wireless Ranging (WiRa) SDK and the other is based on RSSI. DA14531 Social distancing application in also running on the DA14531 TINY Module!

DA14531 disconnect error

Thu, 2021-01-28 03:17 -- wpc

Hi dialog:

  I use DA14531 as peripheral device and found that my program would usually enter 

//We are not in Connected State

in gapc_disconnect_ind_handler at app_task.c when the central disconnects. I checked the state of app task and it's APP_DISABLED. I searched the project and didn't found where the code set the state. So what should I do to locate the problem?

Heart Rate Profile

Fri, 2020-12-18 12:07 -- _asmaitha


I am using the DA14531 soc for our health monitoring project, the use case is to read data from various sensors and transmit the following parameters over BLE:

1) Heart Rate

2) Sp02


4)Body Temperature

I have been able to successfuly create custom service for each of the above mentioned parametres and transmit data over DA14531 but I would now like to use the standard SIG bluetooth profiles to transmit the data.

Laptop to many DA14531 connection

Thu, 2020-11-19 12:40 -- jon479

Dear Dialog Team,

I want my Laptop (Bluetooth Module) to communicate with many DA14531 Modules(>50). The maximum BLE connections on my Laptop are limmited to three. The data I have to transmitt is low and no high throughput is needed. Which option would be the best for me? Bluetooth mesh is not available for the DA14531 module. Is there example code I could use? I'm using at the moment Matlab BLE on the laptop.

Extended sleep mode disable/re-enable

Wed, 2020-09-09 21:23 -- AdamShier



I'm trying to get extended sleep working on my custom board with the DA14581 MOD board. The setup is as follows:


The system is initially configured with extended_sleep without OTP Copy. The wakeup is configured on a button interrupt, which does wake the system up on first press. Upon wakeup, the sleep is disabled (using arch_disable_sleep) so I can sample a sensor every 100ms using the timer0. The extended_sleep is then meant to be re-enabled after 7 seconds. 

Easy to Use, But How?

Hi Dialog,

I want to use DA14531 BLE Module.

BLE Module work with mobile phone. Just do data transfer between. 

I used Codeless and DSPS SDK. I readed about documents. I have an example SDK. I can connect to Da14531 module with Smart ConsoleApp. And I send data AT+MEM related cell. 

I want to use simple application, data transfer via Da1451. I have to create my mobile application. Is it simple Right?

Is it possible to transmit data without using at commands? Could  you explain or what is the easy to way, How can I do that?

Data Transmission Speed for digital sensor

Thu, 2020-06-25 09:34 -- pratikshinde


I want to use DA14531 Tiny Module for reading and transmitting digital inputs to control system placed on 5m distance.

Following is setup, 

4 Digital Inputs  -> DA14531   wireless transmission to DA14531 -> 4 Digital Outputs.

I want to read these inputs at higher frequency lets say 1000 to 5000 times per second. So that I will not miss any change on input side sensors.

Is it possible to achieve this with high data rates over DA14531?

Can we use Tiny Module and DSPS for this purpose?
